Steel Quick Connect Coupler Plug – PM Series – Male Thread R 1/4

This steel quick connect coupler plug (male) from the PM series features a male pipe thread of R 1/4, designed for reliable air flow control in marine pneumatic systems. The compact and robust construction allows for easy one-handed connection and disconnection, making it ideal for shipboard maintenance and repair tasks where speed and reliability are critical.

When mated with a corresponding PM series coupler socket, the plug creates a secure, leak-free seal. The integrated floating ball valve in the socket side automatically shuts off airflow upon disconnection, preventing hose whip and fluid loss. With a working pressure of 1.5 MPa and pressure resistance of 2.0 MPa, this coupler plug is suitable for a wide range of pneumatic tools and equipment onboard.
